Currently using our iChannel portal?

If you’re currently using our existing portal (iChannel) to access documents, don’t worry — nothing is disappearing. All documents —  ones you’ve shared with us and we’ve shared with you — through iChannel will be retained on our end. If you haven’t already downloaded a copy of something you need, just reach out to our team and we’ll get it to you.

iChannel will remain available until September 30, 2026, giving you time to transition at your own pace. After that date, all document access will move to Karbon for Clients, your new and improved portal experience.

Why the move?

A modern upgrade from iChannel: Karbon for Clients offers a more intuitive experience with:

  • Real-time updates on your engagements
  • Direct messaging with your Davis Martindale team
  • Built-in e-signatures, automated reminders
  • Full mobile & desktop access — plus, you can still view and respond to single invoice or request via secure link without ever needing to log in
